These holes run parallel to each other and are located somewhat above the shoulder 24 and at equal distances from the vertical center plane of the plunger drum running parallel to the holes.

The upper end 33 of the stem 23 has a smaller diameter than the main portion of said stem, so that a circumferential shoulder 34 is formed on the stem. A packing ring 35 made from rubber I or any other suitable material is positioned on' this shoulder. I

A sealing bushing 36 comprises a substantially.

cylindrical body 31 provided with a bore 38. In

the inside surface of the body 31 an annular groove 39 is arranged adapted to receive a packing ring 43 made from rubber or any other suitable material. At the lower end of the cylindrical body 31 an outwardly extending shoulder 4| is formed, from which a short round skirt 42 extends downwardly. The inner diameter of this skirt is such that the reduced upper end 33 of the plunger drum stem 23 fits snugly in the skirt 42 and the outside diameter of the short skirt 42 is equalto the outside diameter of the main portion of said stem 23 The under surface of the skirt 42 engages the packing ring 35 located on the shoulder 34 on the stem 23.

A lug 43 provided with a horizontal hole 44 extends upwardly from the cylindrical body 31 for a purpose to be described later.

A plunger rod 45 has a plunger head 46 mounted on its lower end. The head is shaped to fit tightly onto the curved wall portion 30. A threaded nipple 41 is formed centrally on the lower end of the plunger 45 by reducing the latter to a smaller diameter. The plunger head 43, a rubber washer 48 and a metal washer 49 are mounted on the threaded nipple 41 and secured thereon by a nut 50.

The above described parts are assembled as follows:

In the bore 28 of the plunger drum stem 23 a helical spring is inserted and rests with its ,lower end on the stop shoulder 3| in said bore. The plunger rod is inserted in the plunger drum stem bore 28 and through the helical spring 5|, sothat a circumferential stop shoulder 52 on the plunger rod engages thetop end of the helical spring 5|. The, plunger head 46, the rubber 'washer 48and themetal washer 49 are mounted .cn the threaded nipple 41 by the nut 50 so that the plunger head engages the curved wall portion 130 and the rubber washer 48 engages the circular shoulder 23 under the pressure of the spring 5| 'iurging the plunger construction upwardly.

, The packing ring 35 is arranged on the upper shoulder 34 on the plunger drum stem 23 and the packing ring 40 is placed into the annular groove 39 in the bore of the sealing bushing 36. This bushing is forced onto the upper end of the plung er rod 45 until the bottom edge of the short skirt ;42 engages the packing ring 35.

The packing ring 21 is put into the circumferential groove 26 in the skirt 25 of the plunger drum 22 and the packing ring 2| is located in the 'ring groove I8 in the housing I0.

bushing 35 securing the plunger assembly in the housing.

A lever 56 is pivotally connected with the lug '43 on the sealing bushing 36 by means of a pintle 51 extending through the lever adjacent one end thereof and through the hole 44 in the lug 43.

The other end of the lever 55 may be equipped with a plate 58 adapted to be marked to indicate if the spigot dispenses hot or cold water.

To facilitate the attachment or detachment of the cap 53 on or from the housing III a hexagon boss 59 is formed on top of said cap. This boss is provided with a bore 50 to permit the cylindrical body 31 of the sealing bushing 36 to extend slidably therethrough.

The upper end of the plunger rod 45 extends a short distance above the upper end of the sealing bushing and a semi-globular lug BI is formed on the underside of the lever 56 and rests on top of the upper end of the plunger rod 45.

The tabular portion I6 of the housing I0 extends through a hole 52 provided in the wall 63 or the top of a wash basin or the like, so that the bell-shaped flange I2 rests on said wall. A rubber washer 63 and a metal washer 64 are mounted on the tubular portion I1 at the other side of the wall and a nut 55 secures the entire valve construction on said wall by forcing the two washers against it.

A reducing nipple 66 has an outwardly extending flange 61 fitting against the end of the tubular portion I5 and a cap nut 68, in which a rubber washer B9 is arranged secures the reducing nipple to said tubular portion.

The above description shows clearly that the plunger head normally closes the valve tightly by being forced onto its seat by the sprin 5| and the pressure of the water line, to which the reducing nipple 55 may be secured with its reduced end. A slight pressure with the tip of a finger on the free end of the lever 56 suffices to open the valve, which closes automatically and instantly upon releasing the lever 55.

If it is desired to keep the water running for a. length of time, a wheel 91 is rigidly mounted on the pintle 51 inside the hollow lever 56 and is provided in its circumferential surface with transverse slots. Rearward of the pintle a cross wall "II is arranged in the handle 56 having a centrally located opening I02 therein. In the rear wall of the lever 56' a screw bushing I03 is threadedly secured and a lock pin 98 extends slidably through said bushing and the hole I02. A flange I04 on the pin 98 is located inside the lever mits the valve to close.

In Figure 2 two valves of the kind and construction described above have been shown as adapted and arranged to feed a, mixing spout 69.

In this case the two valve housings are provided with horizontal outlet pipes 10 instead of spouts 20. The outlet pipes 10 communicate with a mixing chamber 1 I arranged in the mixing body I2. The top of body 12 has a centrally located depressing portion 13 provided with central hole 14 therein. The upper portion of thewall sur- T e uppe and hi the special m ngle, 5 1

threade =.o w.a l and the tsecurel hl-eadedgnto t is enc l .i above esc bed-.pens ruct en the min e :16 and the s en 5, are adapted tub swung in any'desired position about the iaxisof the nipple.

Kin snou Wi n th b om of th .m z igl ous ne 12a downwardly extending bell-shaped flange .83 is formed ada ted to rest onthe outer or upper sur iace of the Twall of a wash basin or the like.

Centrally of said flange .83 a id ownward ly extending tapped wnippleM is formed onthe bottom of the mixing housing 72. A bolt 85 is screwed int i ip le 84 a te ds h ough a h l "'86 in the basin wall.

A rubber asher 81, a metal washer .88 and a nut tii'on the'boltttat the innersidepf the basin wall secure the mixing chamber .etc. ,in position.

Figure 5 illustrates a modification of the valve described above. In general, the construction of the ,modif ed valve is the same as described, but the ,cylindrieal body 30,01 the .sealingibushing of the modified form is longer .thanthe cylindrical 'body'3'l, so that it extendsibeyond the upper end .of the plunger rod 45, and the hinge lug '43 .is omitted. A push "button 9| has a downwardly extending .Dush rodi92 adapted to fit slidably into the bore of the sealing bushing and to rest on the top end of the plunger rod '45, so that the valve can be opened'by a slight downward push on'thepush button.

To adapt the valve according to my invention for use in connection with a flush tank (not shown) a floatts is rovided with a 'fioa't stem'94, which "is pivotally secured to the lug '43 "by a p'intle 51. The stem 94 is provided with the semi-globular lug '6! resting on-top of the upper end of the plungerrod 45.

Instead of the common spout 22! the valve housing H! is provided with an outwardly and downwardly extending angular outlet 'tu'be 95 leading to thetank (not shown). An upward- '-ly extending narrow tube 9 6 communicating with the'horizontalportion oftheoutlet tube 95'leads to the'overfiowof'the tank.
